[2] The Wolf River rises in the southern Headwaters Wilderness of the Nicolet unit of Chequamegon-Nicolet National Forest, with the northernmost fork stemming from the confluence of Wildcat Creek and Pine Creek at Pine Lake[3] in west central Forest County.

[citation needed] The river flows south through Langlade and Menominee counties, where whitewater rafting is well known.

It finally goes through the village of Winneconne to empties into Lake Butte des Morts on the Fox River.

[4] The Crandon Mine was purchased by the Sokaogon Mole Lake Chippewa Band tribe in 2003 to prevent development that would adversely affect the river.

The tribe has proposed that fishways be constructed around both dams to allow spawning from populations in Lake Winnebago.

However, due to concerns about aquatic invasive species and Viral hemorrhagic septicemia (VHS), a deadly fish disease, the proposal has not yet been implemented, and the capture and relocation program has continued.

Zebra mussels (Dreissena polymorpha) are small, freshwater, bivalve shellfish native to the Caspian and Black Seas south of Russia and Ukraine.

They can clog water intakes and pipes, encrust piers, boats and motors, and cut the feet of swimmers.

It is estimated that the extent of the Lake Sturgeon has dropped to about one-tenth of its population in the state since year 1800.

This species, which has existed since the time of the dinosaurs (100 million years ago), has a viable naturally reproducing population, which are highly prized for the taste of their flesh, and also for their eggs.
